RADIO TUBE sooxnr.

Application filed January 22, 1926. Serial No. 83,008.

This invention relates to sockets for vacuum tubes and especially to that type used in connection with radio receiving sets and the like, and its principle object is to provide a device of this character so constructed that access may be had to the base members and contact clips without the necessity of removing the said tube.

A further object is a means to regulate thetension of the said contact clips.

Particles of foreign matter adhering to contact points andconnections have long been a source of great annoyance to radio users. The open construction of this device, however, eliminates the chief cause of this trouble, as there is no cavity for the dust to settle in, and should any particle stick to a contact point, it may be easily removed.

The socket is of simple and symmetrical form and may be. manufactured at a low cost of production.

In the drawings;

Fig. 1 shows a side View of a vacuum tube of conventional design.

Fig. 2 shows a perspective View of the socket.

Fig. 3 shows a plan view of same.

Fig. 4 shows a fragmentary section on the line H of Figure 2; this View being slightly enlarged.

The invention comprises the following component parts:

A base of suitable material 10, electric terminals 11, 12, 13, and 14, contact clips 15, 16, 17 and 18. Clearance is provided between the said clips and the feet of the standards 19 and 20 which are secured to the base member. Supported by the said standards is a collar 21 which has in the sides thereofbayonet slots 22 and 23. The contact clips above mentioned are made of suitable material, capable of conducting an electric current, and possessing some degree of elasticity, or spring capacity; they are slightly concaved at the free ends, and connected at their outer extremities to the terminal members. Adjusting bars as shown at 24:, 25 etc., support the contact clips near to the middle portions thereof; these adjusting bars rest Within the-grooves as shown at 26, 27 etc., and may be moved at will along the said grooves to provide greater, or less spring tension of the contact clips.

In inserting a bulb of the customary construction in applicants novel socket danger of breaking the glass tubular 'member LS 'with sockets of the usual construction.

eliminated. Ordinary bulbs are grasped,

pressed downwardly and turned While resisting a spring action of some form and in so doing there is a chance of breaking the bulb and severely injuring the person manipulating the same if the spring action is substantially strong.

With applicants device the tension of the spring elements may be temporarily reduced until after the bulb is properly insertedand turned to a locked position in the socket and the spring elements may be t'ensioned thereafter; thus removing the possibility of breaking the tube or injuring the operator and permitting the application of a force of greater strength than is safely attainable It should be understood that a much greater pressure may be exerted on the contact members by the spring elements of applicants sockets than could be safely attained in the sockets requiring the bulb to be inserted against an initial spring action.

The device as shown, is adapted for use with a vacuum tube of the type illustrated in Figure 1 of the drawings; and when so used, the base 28 thereof is inserted within the collar 21 of the socket and the pins 29 and 30 engage the bayonet slots 22 and 23 of the said collar, while the pole pieces asshown at 31,32, 33 etc., rest on the contact clips as shown at 15, 16 etc. In this position it will be seen that the variousmembers arev exposed in such a way as to permit of free access thereto; and it will'be seen further that the pressure of the contact clips against the pole pieces may be regulated as above described.

While I have shown the preferred embodiment of my invention, I do not wish to be limited to the exact form and construction as herewith illustrated, but claim the right to such. minor modifications as may come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is as follows:

1. In a vacuum tube socket, a base of suitable material, electric terminals secured to the said base, and contact clips extending from the said terminals to points concentric thereto, the said clips supported on adjusting bars which rest within grooves in the said base and are adapted to be moved therein to regulate the tension of the said clips,

standards secured to the said base and free from current carrying contact with the clip members, the said standards supporting a collar centrally located 0"81' the free ends of the said contact clips.

2. In a vacuum tube socket, a suitable base plate, electric terminals grouped thereon and contact tongues extending from the said terminals to points central to the said group and having their free ends supported above a clearance space by means of adjusting bars. set within grooves in the said base plate, and a slotted rim centrally supported over the said contact tongues by means of legs resting upon the said base plate, sub stantially as shown and described.

3. In a vacuum tube socket, a bayonet slotted collar supported over a suitable base by means of legs secured to the said base, electric connecting members mounted on thesaid base, and spring tempered contact clips extending inwardly from the said connecting members and having their free ends grouped centrally thereto, and the said clips adjustably supported by bar members resting in grooves in alignment with the said clips, and the whole substantially as shown and described herewith.

4. A socket of the class described comprising a base member, a tubular member 11b mounted on said base adapted to receive the plug of a bulb, spring contact members mounted on said base member adapted to contact with the contact elements of said bulb, and means comprising adjustable bars mounted in recesses in said base member for forcing said spring cont-act members against the contact clements of said bulb after the latter has been inserted in said tubular memher, said adjustable bars being adapted to be adjusted to reduce the pressure of said spring contact members on the contact members of said bulb until the latter is positioned in said socket.

5. A socket of the class described comprising a base member, contact members mounted on said base member adapted to engage the contact member of a bulb when the latter is positioned in said socket, and adjustable means mounted on said base member adapted to permit said spring contact members to be pressed downwardly freely during the insert-ion of said bulb in said socket and to be positioned after insertion of said bulb in said socket for causing said spring contact member to be firmly pressed against the contact members of said bulb.

In testimony whereof I have affixed my signature.
